To all whom it may concern.-

Be it known that I, RICHARD H. STEVENS, of Munhall, Allegheny county, Pennsylvania, have invented a new and useful Metal-Turning Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevation showing my improved metal-turning apparatus as it is applied to a hotbed for turning metal beams. Fig. 2 is a detail side elevation of the turning mechanism, showing the positions assumed by the apparatus when about to turn a beam and after the beam is turned on the hotbed. Fig. 3 is a plan view showing a part of a hotbed and the manner in which a number of turning-arms are arranged to be operated by one turning-cylinder.

My invention relates to the class of devices for turning metal beams or other metal on a hotbed, a roller-table, or other suitable support.' Heretofore where these devices have been employed on hotbeds it has been necessary to move the metal away from the turning-up device before such device can be returned to its inoperative position. The reason for this is that the portion of the turn-up device which contacts with the flanges of a beam will lie beneath these flanges and prevent the return movement of the turn-up device until the beam is moved sidewise out of the path of this portion of the device.

My invention overcomes this difficulty; and it consists in providing the turn-up device with a movable member which will be withdrawn when the metal is turned up, thus.

allowing the device to be returned to its original position without moving the beam or other metal operated upon.

In the drawings, 2 represents one of the rails of a hotbed, these rails being spaced apart, so that the pushing-dogs 3 may push the beams along the support, these dogs being actuated in any desirable manner, such as by the wire ropes 4, connected to the dogframes.

At any suitable point in the width of the hotbed is located a shaft 5, having a segmental gear 6, actuated by rack 7, connected with the moving element of a motive cylinder 8. To this shaft are secured the turn-up arms 9, which normally lie in the position shown in full lines in Fig. -2. Each one of these turn-up arms is perforated transversely to receive a bar 10, which slides through the hole and is pivotally connected at 11 to a lever 12, fulcrumed at 13 on the arm 9. weight 14 is adjustably secured to the other arm of the lever 12, this weight being sufficient to draw back the bar 10 within the hole in the arm when the weight of the beam is taken off this bar. The hole for the bar is preferably cham'fered or cut away, as shown at 15, to allow free movement of the .pin without binding.

In the operation of the device when the beam has been brought to the position shown in full lines in Fig. 2 by the push-dogs the cylinder 8 may be actuated and the beam thus turned up into vertical position, as shown in dotted lines in this figure. As soon as the weight of the beam is taken on the rails of the hotbed in the movement of the turn-up arms the weights 14 will draw back the bars 10 within their holes, as shown in dotted lines. The arms may then be swung back to their normal inoperative position without contact with the beam. In this return movement at a certain angular position of the arms the weights will return the bars to their normal projecting position and hold them in such position ready for the next beam to be pushed against them.

I have shown the ends of the arms as projecting within the rollers of the feed-table; but the length or location of the arms may be changed as desired. To provide for moving the beams or metal over and past the arms when it is not desired to turn such metal, I provide a hole 16 in each bar 10. By manually pulling down the bar and inserting a small pin or stop through this hole I can hold the stops down out of position.

The advantages of my invention will be apparent to those skilled in the art.

first to provide the arm with the movable stops or pins.

I claim 1. In a turn-up mechanism, a tilting arm having a movable bar or slide therein, and

The auto- .matic withdrawal of the arms and bars saves IIO connections for Withdrawing said bar; sub- 4. In a turn-up device, a tilting arm having a hole or guide therein, a transverse bar in said hole, and a Weight for automatically Withdrawing the bar when the Weight of the beam is removed from it; substantially as described.

In testimony whereof I have hereunto set 20 my hand.

RICHARD H. STEVENS.
